This quarterly progress report describes NBS activities directed toward the development of methods of measurement for semiconductor materials, process control, and devices. The emphasis is on silicon device technologies. Principal accomplishments during this reporting period include (1) completion of Hall effect measurements to determine activation energies of the gold donor and acceptor levels in silicon; (2) successful direct measurement of fast interface state density with the circular CCD test structure; and (3) demonstration of the feasibility of the use of acoustic emission as a non-destructive means for testing individual beam-lead bonds.

This report describes the activities of DoD personnel, both military and civilian, in Shots WASP, MOTH, TESLA, TURK, and HORNET, the first five events of the TEAPOT atmospheric nuclear weapons test series. The tests were conducted from February 18 to March 12, 1955 and involved participants from Exercise Desert Rock VI, AFSWP, AFSWC, AEC nuclear weapons development laboratory test groups, and the Civil Effects Test Group. This volume also describes the radiological safety activities undertaken at each of these five shots.
